# influxd upgrade

This page documents an earlier version of InfluxDB OSS. [InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

#### API token hashing is enabled by default in InfluxDB OSS 2.9.0

Stronger token security: tokens are stored as hashes on disk, so a copy of the database file doesn’t expose usable tokens. Existing tokens are hashed on first startup and the original strings can’t be recovered afterward — **capture any plaintext tokens you still need before you upgrade**.

For more information, see [Token hashing](/influxdb/v2/admin/tokens/#token-hashing).

Use the `influxd upgrade` command to upgrade an instance of InfluxDB 1.x to InfluxDB 2.9. This command copies all data in [databases](/influxdb/v1/concepts/glossary/#database) and [retention policies](/influxdb/v1/concepts/glossary/#retention-policy-rp) (used in 1.x) over to [buckets](/influxdb/v2/reference/glossary/#bucket) (used in 2.9).

Be sure to back up all data before upgrading with `influx upgrade`.

This command performs the following actions:

1. Creates the InfluxDB 2.x configuration file using 1.x configuration file options. Unsupported 1.x options are reported to standard output. If the configuration file is not available, the 1.x database folder can be passed via th `--v1-dir` flag.
2. Copies and upgrades 1.x database files.

The target 2.x database directory is specified by the `--engine-path` option. If changed, the bolt path can be specified by the `--bolt-path` option.
